Current Switch: Action musimboti uye kukura

Vazhinji namano kuti ushande ari magetsi matunhu, dzinoda zvinonyatsochengeta kuyerwa munguva chaiyo. Kururama nezviyero izvi zvinoenderana zvinhu zvizhinji: unhu kudzora pezvakaitwa iri kudzorwa matunhu, akavimbika anoita kudzivirira, dzemaitirwe apo pakuverenga simba kudyiwa mune magetsi zvivako, etc. Kazhinji vakadaro kuyerwa vachishandisa anokosha namano kuti vari chikamu redunhu huru. Somuenzaniso, zviri kuitika Switch zvinowanzodavirwa kushandiswa mubasa mano mazhinji. Rinogona chinozoiswa dzakasiyana-siyana zvinhu, zvichienderana chaiwo redunhu kugadzirwa. Zvazvinosarira kuzochinja chete nheyo huchishanda - maererano ine coefficient midzi mukati maro, izvozvo vatendeuki chiratidzo kubva chiridzwa transformer kana zvimwe mudziyo kuva voltage chiratidzo riri vachiwirirana nevamwe redunhu.

Kusiyanisa ano Switch, iro rakagadzirirwa kushanda mumatunhu AC uye, naizvozvovo, kugara voltage. Somuenzaniso, funga mabasa neimwe. Nokuda rakatumbuka voltage sezvo tambo chinhu ari yemanyorero kushandiswa kuitika transformer. Izvi contactless mudziyo iyo monitors mamiriro mukuru redunhu kudzorwa. The chiratidzo pairi uye akapa kuti magetsi Switch, ane chinangwa - kuti kukwira kuti wakagamuchira chiratidzo kudzora redunhu.

Situation siyanei kana tiri nevanhu kugara kana zvishoma nezvishoma siyana parameter. The pamusoro-akatsanangura transformer mune zano rakadaro asingadi kushanda, kubvira kwayo goho tinogona kuwana chete simba rinomutsa ari kuyerwa parameter. Kazhinji, mune zvirongwa zvakadaro, chaiyo shunt pamwe yakawedzera hama kuna mamwe redunhu nemishonga. Zvinonzi hwavapo zvakananga pamusoro mutsetse. Panyaya iyi, akabvisa ari voltage donhwe panguva mugove ichi, izvo achapiwa uye wokutepfenyurisa DC. Sezvo chiyamuro redunhu pazano yakadaro vari mukuru kwaniso, ipapo Switch uyu anoita akawanda mabasa. It galvanically Anopatsanura simba uye kuyerwa mumatunhu panguva anorwisa akagamuchira chiratidzo.

Typical schema anoshanda ane kuitika Switch rine kupomba jenareta dzakakwirira kakawanda, uye kiyi kuparadzana transformer. The kuuya tambo chiratidzo iri mudzoke neshoko jenareta uye kuparadzanisa kiyi kazhinji vakaungana FET. The rakatumbuka voltage nokudaro kutendeuka iri chakasvitswa imwe nevamwe transformer. Zvino yava yakasvinwa uye Amplified zvichienderana reshiyo kuti midzi muna magadzirirwo.

A siyanei musimboti kushanda kuradzikwa inonzi Hall-ano Switch. It anoyera kusimba remagineti, izvo unovapo nokuda magetsi chokubuda iri kondakita, uye vatendeuki ive goho voltage chiratidzo. A chinoratidza basa rake ndechokuti waifarirwa anokwanisa ishande kuitiswa mumatunhu ose. sensors kwakadaro chiine vane zvakanaka unongotaura unhu.
